# ao-chaosread(1)

read raw noise source from chaoskey

## NAME

ao-chaosread - read raw noise source from chaoskey

## SYNOPSIS

**ao-chaosread**

## DESCRIPTION

*ao-chaosread* reads ADC values from the noise source on the attached ChaosKey device.

## OPTIONS

- \-s serial \| --serial serial

  This selects a ChaosKey by serial number instead of using the first one found.

- \-l length \| --length length

  Set the amount of data to read. Suffixes 'k', 'M' and 'G' are supported. The default is 1k.

- \-i \| --infinite

  Read an unlimited amount of data.

- \-b \| --bytes

  For each 16-bit value read, output bits 1-8 as a byte, don't output bit 0 or bits 9-15 at all.

- \-c \| --cooked

  Read whitened data from the device. The default is to read raw data from the noise source.

- \-r \| --raw

  Read raw data from the noise source. This is the default.

- \-f \| --flash

  Read the contents of flash memory on the device. This loops through flash memory, so you can read the contents more than once, but there's no way to reset the pointer back to the start other than making sure you read the whole contents.

## USAGE

*ao-chaosread* reads noise data.
